I agree with you. If you are never going to walk in your shoes, or do only very limited walking, then go ahead and get SPD-SL or some other road pedal as the platform will have a bigger surface area and will be more comfortable over longer, more intensive rides.
SPD is what you would wear if you want to walk in your shoes. They are not as comfortable as normal shoes, but still quite usable actually.
